The utility model relates to a kind of conductor rail, in particular for the conductor rail of the direct voltage in middle pressure scope, has at least two by the separated conductor of insulator, wherein, described insulator is arranged between described conductor, and wherein, described insulator exceedes described conductor and stretches out.
Background technology
In motor, the electric current of the voltage in conventionally guiding by conductor rail within the scope of pressure.Conductor rail is conventionally also known as bus or is called conductor rail, but uses this concept of conductor rail below.Because this conductor rail mostly can not prevent independently particle, for example dust or particulate and other spots from surrounding air and deposit near on the surface of conductor, these spots may affect insulating properties.The layer being made up of the particle on insulator surface may cause leakage current together with the electric field between conductor.These leakage currents are reasons that the very small region in this stratum granulosum becomes dry.So, the region of exsiccation just has obviously higher resistance, causes thus very high electric field strength.These first local electric fields that occur are as the starting point of controllably not discharging.Especially this effect of mentioning below especially can cause impact until the assembly that destroys conductor rail and/or connect.For those for transmitting voltage within the scope of pressure to control for the conductor rail of large-size machine, leakage current and electric discharge may cause the damage of current transformer.Except high maintenance cost, this also causes the fault of motor conventionally.So far, attempt avoiding by cleaned at regular intervals conductor rail the generation of this situation.Because for clean, conductor rail must be in most of the cases only palp, this way has also been brought high maintenance cost.

Summary of the invention
The purpose of this utility model is, improves the insulating properties of each conductor of conductor rail, and protection insulator prevents the pollution due to particle deposition.
This object is achieved by a kind of conductor rail, it is in particular for the conductor rail of the direct voltage in middle pressure scope, have at least two by the separated conductor of insulator, wherein, described insulator is arranged between described conductor, wherein, described insulator exceedes described conductor and stretches out, and it is characterized in that, described insulator surperficial exceedes a part that described conductor stretches out to be furnished with and to leave a blank, and described conductor has laminar structure.
In addition, this object is also achieved by a kind of method.
Insulator stretches out conductor and not only reduces particle deposition on insulator, and extended leakage current by a conductor to another conductor must process distance.This has just been avoided formation leakage current, the useful life of having improved thus conductor rail constantly.On the one hand, insulator must fill up the whole volume between conductor.Insulator exceed part that conductor edge stretches out make stratum granulosum the surface area that must cover significantly become large.Additionally, at least both direction is pointed in the outside of insulator.Thereby just reduce particle and accumulated in the possibility on each side.In addition, the electric field strength in the perimeter of conductor rail is obviously lower.All these is more unfavorable to leakage current.Another kind avoids the scheme of the particle deposition on conductor to be to cover adventurous region by an extra play.This layer is for example made up of flexible plastics, and preferably joins by the outside of bonding connection and conductor.Extra play also can be made up of the extension of the lamination of one or two conductor, wherein, again preferably realizes the combination of lamination by bonding connection.In the category of safeguarding, installed additional additional insulator and/or extra play in the conductor rail of running status, just obviously improved useful life and additionally reduced essential service intervals.If a part of loosely of extra play is arranged on conductor rail and thus in freely activity partly, so, just may be because air-flow causes its motion.This motion may react on the deposition of particle.
In a kind of favourable design, a surperficial part for insulator exceedes conductor and stretches out and be furnished with and leave a blank.These are left a blank and may have the shape of rectangle, and they are parallel to conductor and extend along the surface of insulator.Leave a blank the sedimentary deposit that may occur is interrupted partly by these, because some surf zones are by air-flow protection.In addition, also extended the stroke that leakage current must pass through originally.Therefore, do not depend on the position of conductor rail, effectively suppress controllably not discharge this trend.
In the favourable design of another kind, described insulator is made up of plastics and/or inorganic composite materials, and described insulator part ground or fully surround conductor.Be mainly used in the inorganic composite materials of high pressure range, for example pottery just has very high useful life, and scratch-resistant quarter.Because serving as reasons, the input of the ceramic insulator forming on manufacture is produced is higher, thereby can select plastics in middle pressure scope.Especially preferably select thermoplastics to be used for the insulation of conductor, because it can be because heat be out of shape and and then simplification manufacturing process.Utilize the further insulator being formed by plastics also can realize more simply installing additional existing conductor rail.The thermoplastics being made up of the group that comprises polyester and polypropylene or polystyrene is because it is compared with high breakdown characteristics and very applicable.If require to have higher thermal stability, the inorganic composite materials that so just should select in middle pressure scope.Also can apply the combination of this bi-material.
In the favourable design of another kind, described insulator is made up of multiple layers.According to this configuration, just there is this possibility, that is: the various combination of insulating material is combined, and improve on the one hand thus breakdown characteristics, and improve especially the electric field strength near edge, end or the similar pointed shape of conductor simultaneously, also reduced by selection material compatibly the dangerous probability occurring.
In the favourable design of another kind, the surface of each layer is also not parallel to the surface of conductor, and/or described layer is of different sizes specification.This design comprises for example two insulators that be pushed into one another, wedge shape, described insulator after being pushed into one another because static friction forms and being fixedly connected with of conductor.
In the favourable design of another kind, the surface of insulator is furnished with the coating that can conduct electricity.The coating that can conduct electricity is for example made up of a kind of polymer that can conduct electricity.In this design, resistance should be in the scope of begohm (10^9Ohm).Can effectively derive the leakage current that may occur by this coating, this is because the resistance of the coating that can conduct electricity is less than the resistance of stratum granulosum conventionally.Thereby avoid the local exsiccation occurring of stratum granulosum, and therefore stoped the regional of high electric field strength.
In the favourable design of another kind, fix like this extra play, make exist-to limit by extra play, insulator and/or conductor-gap.Extra play is preferably flexible band, not guide current of described band, and it is for example made up of paper, plastic film or silicon materials or elastomeric material.In addition, extra play covers the lateral surface of insulator and conductor, has avoided thus particle deposition on described insulator and conductor.Due to the flexibility of extra play, this extra play can move due to the air-flow that may exist.Particle is just difficult to be deposited on well the surface of motion, is on the extra play being made up of flexible material in this case.Additionally, these particles may be open again due to distortion conventionally.This variation of extra play is if by realizing with the interaction of the air-flow around conductor rail or by causing for this air blast or nozzle specially.Even if under the penetrating condition of stratum granulosum, also significant prolongation the stroke of leakage current.But a significant advantage of this design is, this extra play can be arranged on existing conductor rail in simple mode, and therefore no longer must change or intricately expands existing insulator.But this extra play is not limited in and is just applied to like this conductor rail, but can also be arranged on other positions that are subject to leakage current threat, and promote thus the lifting of security performance.
In the favourable design of another kind, conductor additionally has laminar structure (Laminierung).Laminar structure can react on conductor due to the impact being subject to contacting of its surrounding environment, and in the time of manual maintenance, has formed the anti-protective that touches.In addition, laminar structure also provides and has prevented that conductor is subject to mechanical sex protection, and prevents due to airborne oxygen oxidized.
A kind of advantageous applications of this equipment is conductor rail, is particularly useful for the direct current within the scope of middle pressure, comprises the equipment for insulating.Conductor rail especially has extensive use at switch cubicle or in industrial processes, and at this, multiple power consumption equipments will be connected in parallel with a voltage source.Additionally, power consumption equipment can be on the diverse location of conductor rail tapping voltage, and may also can move and not lose contact along conductor rail.The remodeling to insulation proposing causes higher fail safe and lower maintenance needs.
